Abstract

A method of combining phase-interferometer direction-finding and digital channelized receiving is adopted to provide angle of arrival information for signal sorting in passive guiding system. The method can realize multiple signals receiving simultaneously and digital phase discrimination. A method of high efficient channelized receiving based on polyphase filter structure and digital phase demodulation is raised according to signal real-time processing requirement in passive guiding system. The existing problems in the method which applied to passive guiding system is studied. The result indicates that structure and method are valid via construction of digital channelized receiving system and testing.
